Breeding leos is a cinch. Besides what everyone else said, I wouldn't breed the female all that often, and ALWAYS keep the sexes separate. They only lay two, sometimes one, egg(s).Breeding the female too often, or keeping her with the male may cause her to waste away, as the eggs are fairly lrage compared to body size, and very taxing on the girl. When you put them together, they should mate within minutes.....usually.
